Subject: [PATCH 1/7] Make sure dirent is available on MSVC

It is a header only library with a single header (dirent.h). vcpkg installs this header with a custom logic to the global include path. However in other environments without modification upstream has to be treated like a usual library n cmake. "Linking" against the interface makes sure, that it is found and that the include paths are available for us. To conver both scenarios we use a FindDirent.cmake

Subject: [PATCH 2/7] Don't require Kwalify for tests on MSVC

Kwalify is used to validate MLT's YAML files, but it is not available for MSVC easily (eg. via vcpkg). This is only relevant for local setups, because for CI it is covered by other plattforms and the results of YAML validation are plattform independent
